The health authorities of the United States announced Thursday that 18 people have died and more than a thousand have been affected by mysterious lung injuries linked to electronic cigarettes of flavors and liquid nicotine for vaping.
In less than a week, the number of cases has grown by 25% from 805 last week to 1,080 in this, according to data published Thursday by the government Centers for Disease Control and Prevention (CDC).
According to the federal agency, most patients admit to having used products that contain tetrahydrocannabinol (THC), the main psychoactive component of marijuana.
For that reason, the CDC notes that “the latest national and regional findings suggest that products containing THC play a role in the outbreak. “
Figures and affected
Of those affected, 70% are men, 80% are patients under 35 years of age and 16% are under 18, while 21% are in the age range from 18 to 20 years.
Several experts in the marijuana industry have warned that substances are used in the black market to thicken THC oil, including a derivative known as vitamin E acetate, and believe that this could be playing a role in lung lesions. .
However, the authorities have not yet identified any product or substance as responsible for the disease.
This same Wednesday, a group of scientists from the Mayo Clinic in Rochester, Minnesota, published the first study of lung tissues with patients suffering from vaping.
The scientists explained that toxic chemical vapors, and not the presence of lipids in the lungs, are the cause of the damage caused by electronic cigarettes.
The investigation found no evidence of lipid accumulation – fatty substances, such as mineral oils – in the lungs, a factor that had been pointed out as a possible cause of damage from the use of electronic cigarettes.
These scientists analyzed the biopsies performed on 17 patients, all with pulmonary lesions related to vaping
